Well, he won the title for CFC.
Then he joined us and won 2 trophies in his first year. In his 2nd year, he finished 2nd (with a squad which was far from great). To put this into context, this season, we are hovering mid-table and some fans are accepting that it may be several years until we reach the dizzy heights of 2nd place.
It bemuses me that fans cannot look at the facts objectively.
The problem at Spurs is that he won't have a big budget to spend and that just isn't very Mourinho like. Unless of course he sells Kane, then uses that money to rebuild the squad to his liking. That could work.
